Experiments

Detection and attribution (D&A) studies typically require unforced control simulations and historical
simulations including all major anthropogenic and natural forcings.
Such simulations will be carried out as part of the CMIP6 DECK and the
CMIP6 historical simulation. In addition D&A studies require
simulations covering the historical period driven by individual
forcings or subsets of forcings only: these will be undertaken as part of DAMIP. Key novel features of the DAMIP experimental design following D&A-relevant simulations in CMIP5 are:

new historical simulations of aerosols-only, stratospheric-ozone-only, CO2-only, solar-only,
and volcanic-only forcing, facilitating an improved estimation of the
climate response to individual forcing;
